In this thesis, we present approximation algorithms for various NP-hard vehicle routing problems, as well as for a related maximum group coverage problem. Our main contribution is a framework to build good constant-factor approximation algorithms for variants of the multi-depot $k$-travelling...

Coupling supercritical CO2 extraction with membrane separation leads to energy savings by recycling CO2 at supercritical state while separating extract components. Commercially available polyamide-based membranes are commonly used with coupled systems due to their availability and robust...

A flag of a finite dimensional vector space V is a nested sequence of subspaces of V . The symplectic group of V acts on the set of flags of V . We classify the orbits of this action by defining the incidence matrix of a flag of V and show- ing that two flags are in the same orbit precisely when...

In this paper we find irreducible characters of G=SL(k,Z/p^nZ) where n >= 2, k=2,3 and, p is an odd prime. In the case k=2 we give a construction for every irreducible character of G without calculating the character values. Our method is based on finding a normal subgroup of G and applying...

Little is known about Vertex Operator Algebras (VOAs) which are neither semi-simple nor rational, and most of the work on such VOAs has been focused around specific examples such as the Singlet VOA. In this thesis, the relationship between subcategories of the module categories of the Singlet VOA...

Periodic solutions and bistability in a model for cytotoxic T-lymphocyte (CTL) response to human T-cell lymphotropic virus type I (HTLV-I)
DownloadFall 2009
HTLV-I is the first discovered human retrovirus and a causative agent of both adult T-cell leukemia (ATL) and HTLV-I-associated myelopathy (or tropical spastic paraparesis) (HAM/TSP). Previous models have been successful in providing insight into the progression of HTLV-I infection. The...

The traditional approach to the study of consumer behaviour is to regard them as isolated islands of preferences, needs, motives, and goals; however, this approach neglects the impact of ‘others’ on consumers’ judgments and preferences. For this reason, the theme of this thesis is the ‘connected...
